Again, you're confusing Trump's position as a nationalist with being pro-Russian. Trump is not a Russian ally, he already would have pulled out of Ukraine and NATO, and would not be attacking Iran, Cuba, and Venezuela.
As for the Chilean nationalists, I never said they weren't working class. I am specifically saying that individual groups can be bad, but if they are fighting against indigenous peoples then this is definitely reactionary. This is why I recommended reading Fanon, I of course oversimplified the situation, and gave the trade union example to illustrate that exceptions exist.
